The Twelve Chairs (1962)

When her country is taken over by socialist revolutionaries, a wealthy woman can't bear to give up all of her wealth and possessions to the new government, so she hides her jewels in one of the 12 chairs of a dining-room set. After her death, her nephew finds out what she had done and, since the chairs had been "nationalized" and are now in the possession of a dozen different people, he sets out to track them down and get the jewels he believes rightfully belong to him.
